I am creating a transformation where I am joining data from two different views/containers, where table B has a node reference to table A. I have tried to find documentation for this, but I have not found any so far. Through friends and trial and error I have found two options, and neither seems to be performing well. Example:Type A { Name: String}Type B{ Name: String A_ref: A}What I have found as possible solutions are to go through cdf_data_models and picking the externalId from the node-reference:from cdf_data models(<spc>, <mod>,<ver>, “A”) as A join cdf_… as B on A.external_id = B.A_ref.externalIdSame as above, but join on a as a nodereference: on B.A_ref = node_reference(<spc>, A) Neither of these options seems to be documented anywhere, and I can’t find any other ways documented. The performance when reading when using these joins seems slow, even though I have set up a few indexes which should cover the different joins. This is also slower then

which types of files supports (read directly) for P&ID and 3D model with CDF ?
Missing features for granting or excluding access to certain spaces based on a regex pattern. Permissions for data model and data model instances should be divided into read, write, create, edit delete, and update actions by scope.
Imagine the Reporting Site and the Reporting Unit entities, 1 reporting site has N reporting units.Currently, If I am in the Reporting Site entity, there is no way to filter reporting sites based on a reporting unit condition using graphql. Like: Give me reporting sites that have reporting units with the name "CLKVAM" to solve that , we need to go to the reporting unit level and query using a reverse edgewhich makes data modeling and querying more complex ... sometimes we even need to do some transformations to remove duplicated data
Great work on the tool, it will let us remove a few pounds of CICD scripts.Listing some feedback here (as advised by Jan Inge).Will you supply patterns or guidance for structuring the custom modules. Do you have any thoughts on which level a project should group their artifacts into a module.Is there a plan for added support for the development lifecycle, e.g. downloading a full solution as configuration (from existing project), download buttons on other resources than transformation (e.g. datasets).It would perhaps be better to let the RAW config support multiple tables (one per DB), one file per table seems a bit bloated. A “Download CLI” on the DB level would also be great.Is it possible to have the auth verify command also check transformation credentials?Not directly related to the tool, but it seems to be a mismatch between tranformation credentials configuration in the UI and via the tool. We cannot configure the advanced scenario in the UI, and we cannot verify the auth via the
The ability to pin latest values to a drawing in canvas is fantastic, but on most our assets we have more than one timeseries linked to that equipment. Is it possible to add the ability to pin several timeseries to the same equipment. Also to pin additional timeseries that is not contextualized to any asset on top of a document/file/drawing.In addition for consumers of the content the context of the value is needed, so we need the ability to show units like in the old infographics.
What are the permissible size of file can upload in CDF ? Which type of P&ID files are directly read in CDF ? Which type of 3D Model files are directly read in CDF ? Is any converter tool is available in CDF for conversion of file in to require file format for P&ID and 3D model in cognite data fusion ?
This post is pursuant to “Postman does not work properly after authorization”.I have begun the module:Followed the steps in the instructions.Environment variables: Authorization was updated: Then, to test, I went: Cognite API collection > "Assets" folder > "List assets" > SendThis gives Error - different to that in post “Postman does not work properly after authorization” - Next, I try to list the timeseries data: timeseries > list time series > Send. Whereas in post “Postman does not work properly after authorization”, I got back data, now I get Q1. Please could someone help me get around this?Thank you for your support. Regards,Doug
Is there a way to query metadata of TimeSeries from a particular dataset in CDF Transformations?Something like this, but this query isn’t workingselect cast(`externalId` as STRING) as externalId, cast(`dataSetId` as STRING) as eidfrom `_cdf`.`timeseries`where dataSetId == <data_set_id>;
What access capabilities do I need to run transformations as “Current User”. I have a user who don’t see “Run as current user” as in screen shot. Next screen shot is mine, and I can see it probably because I am added as admin
Hello everyone. We have some checklists where the operators measure the length of something, usually in feet and inches, like 1’10”. We have been facing some trouble creating tasks with this type of data on the templates, we could only add decimal numbers. How have you been handling this type of data?Thank you.
Im trying to create a new function in python, when I run this function from local it works fine but when I run it from cdf service it does not work. I got this error message: CogniteAPIError: <!doctype html><html lang=en><title>500 Internal Server Error</title><h1>Internal Server Error</h1><p>The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.</p> | code: 500 | X-Request-ID: 04b27193-d865-98d5-8a2a-11b94126e8eb
I have begun the module: I followed instructions down to setting the environment variables:Then, authorization was updated: Get New Access Token is successful. Use Token clicked Then, to test, I went: Cognite API collection > "Assets" folder > "List assets" > SendThis gives Error: So, I deselect “minCreatedTime” parameter. (THERE IS NOTHING in the documentation that talks about this.) The, press “Send” again.But then get this error when testing:So, deselect “maxCreatedTime” , and progressively deselect minLastUpdatedTime; maxLastUpdatedTime as indicated by error messages.Finally, Gives the error: Therefore, my attempt to list the assets in the CDF project has failed. Next, I try to list the timeseries data: timeseries > list time series > SendTry deselecting all the query parameters > Send This time there is a listing of timeseries: My questions:Q1. Why can I not list assets?Q2. Why can I list timeseries, but not assets? Thank you for your support. Regards,Dou
